DEVICE FOR SECURING PICKERS TO LOOM PICKER-STAFFS.

SPECIFICATION forming part of Letters Patent No. 561,269, dated June 2,1896.

Application filed March 2 7 l 8 9 6.

To all whom, it may concern.-

Be it known that I, WARD B. MOODY, a citizen of the United States,residing at Blackstone, in the county of Worcester and State ofMassachusetts,have invented certain new and useful Improvements inDevices for Securing Pickers to Loom Picker-Staffs; and I do declare thefollowing to be a full, clear, and eX- act description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates. to improvements in devices for holding pickers onpicker-staffs and it has for its general object to provide a cheap andsimple picker-holder Which may be quickly and easily secured upon apickerstaff, and one which when properly secured upon the staff will notbe liable to be loosened by the shock and jar to which pickers andpicker-staffs are ordinarily subjected.

Other objects and advantages of the invention will be fully understoodfrom the following description and claims when taken in conjunction withthe accompanying drawings, in which Figure 1 is an elevation, partly insection, illustrating my improved device as holding a picker on apickenstaff. Fig. 2 is a similar view taken at right angles to Fig. 1.Fig. 3 is a transverse section taken in the plane indicated by the line00 w of Fig. 1, and Fig. 4 comprises perspective views of thepickerholder and the devices by which it is fixed 011 the picker-staff.

In the said drawings similar letters designate corresponding parts inall of the several views, referring to which A indicates a picker-staff,which may be of the ordinary or any suitable construction.

B indicates the picker, which may be formed of any suitable material inany desired manner, and O indicates the holder which receives the pickerand secures the same to the pickerstaif A. This holder O is preferablyformed in one piece, of metal or other suitable material, as bettershown in Fig. 4, and it comprises the body portion a, which ispreferably of the form shown, although it may be of any other suitableform, and is provided with an inwardly-directed flange b to retain thepicker within it, and the resilient arms 0, which are designed toreceive the staff A between them,

as better shown in Fig. 3, and are provided with shoulders cl, betweenwhich and the body a the staff is interposed, as illustrated. Theforward portions 6 of the arms 0 are provided with alined transverseapertures f to receive the fastening-bolt D, and one of said portions eis provided in its outer side with four (more orless) grooves g,designed to receive the four (more or less) protuberances h on the innerside of the nut E, which is mounted on the bolt 1), as shown. Theportion 6 of the other arm 0 is provided in its outer side with one ormore grooves or seats 1', which are designed in practice to receive theprotuberance j upon the head k of the fastening-bolt, as better shown inFig. 8 of the drawings. The arms 0 are furthermore provided upon theirinner sides with the barbs Z, which are designed and adapted to takeinto the staff A, as shown in Fig. 3, to better fix the picker-holderthereon.

In applying my improvements to a pickerstaff the picker B is placed inthe holder C, after which the picker-staff is inserted between the arms0 of the holder, as illustrated. The bolt D is then passed through theapertures f of the arms 0 until the protuberance on its head rests inthe seat 1; in one arm 0, and the nut E is turned upon said bolt untilthe protuberances on its inner side engage the outer side of theadjacent arm 0. As the said nut is tightened it will be seen that thebarbs Z will be sunk into the sides of the staff A, and will assistmaterially in securing the holder on the staff, and when the nut issufficiently tight it is left with its protuberances h resting in theseats or grooves g of one of the arms 0, as shown. In virtue of this andthe fact that the protuberance on the bolthead rests in a seat 2' of theother arm 0 and the said arms 0 are resilient it will be seen that boththe bolt and the nut will be effectually prevented from working loose,no matter how much shock and. jar the picker and pickerstaff aresubjected to, as the arms 0 will exert an outward pressure against thenut and bolt head, and will consequently retain the protuberancesthereof in the grooves. The arms .0, by reason of their resiliency, willgive inwardly when the nut D is tightened, and consequently will notprevent the nut from turning upon the arm which it impinges against.

It will be seen that my improved holder IOC may be made almost ascheaply as the ordinary picker-holder, and may as quickly and easily beplaced on a picker-staff to secure a picker thereto. It will also beseen that the holder embodies no parts that are likely to gctout oforder after short use, and consequently it will outlast a great numberof pickers. It will further be seen that while the picker-holder is notliable to be loosened by the shock and jar incident to the operation ofthe loom it may be readily removed from the picker-staff when it isdesired to replace a worn-out picker by a new one, which is an importantadvantage.

Having described my invention, what I claim is 1. The combination of apicker, a pickerstaff, the picker-holder comprising the body containingthe picker, and the resilient-arms resting on opposite sides of thepicker-staff and provided with barbs adapted to sink into thepicker-staff and with alined transverse apertures and each having a seatin its outer side, the bolt extending through the apertures of said armsand having a protuberance on its head adapted to take into the seat ofone of the arms, and a nut mounted on the bolt and having a protuberanceon its inner side adapted to take into the seat of the other arm,substantially as specified.

2. A device for holding pickers and securing the same uponpicker-staffs, comprising the holder having the body portion adapted toreceive a picker, and resilient arms provided with alined apertures andeach having a groove or seat in its outer side, the bolt extendingthrough the apertures of said arms and having a protuberance on its headadapted to take into the groove of one of the arms, and a nut mounted onthe bolt and having a protuberance on its inner side adapted to takeinto the groove of the other arm, substantially as specified.

In testimony whereof I al'fix my signature in presence of two witnesses.
